EU was cozy with US cloud operators which built and ran datacetners in the EU soil. They have special agreements for data isolation and data travel limitationss (i.e.: Data can't leave the said datacenter or the continent).

After the last election, they decided that it's not safe in the long term, and started to build their own infra. It'll take some time.

Yes exactly. It's hard to understate the shock that happened to the deep trust that existed between the EU and US. And I don't think that will return even if the US changes back. Trust is hard to build and easy to lose.

True, but why did they trust the US so much in the first place? It is not as though no-one has ever warned of the dangers before this year!

Given that one of the EU's aims is to be a peer to the US and China (the term I recall them using is a "multi-polar world") they should not be reliant on anyone to this extent.

Similar background, a long history of standing together (e.g. the war, marshall plans, NATO etc)

Trump is pretty unprecedented, even though some previous presidents weren't very friendly with the EU (like the "Freedom Fries" issue under George W Bush, when France opposed the invasion of Iraq - which eventually ended up based on complete lies so the French were totally right).

True. Europe has been too comfortable with the situation. It's also because it's hard to get everyone aligned. Politics is very nation-aligned, not EU-aligned.
